Jesper photographed the incident with his mobile phone. Now the men (two policemen in undercover outfit) started to attack and harass him instead. They threatened to take him in custody and perform a drug test etc if he didn't delete the pictures from his mobile phone. So he erased the pictures, supervised by the policemen.

This could have been the end of the story. But Jesper managed to recover the photos and also a film documenting the incident. Amazing guy, amazing stuff.
